WILLIAM C. YOUNG, OF DANVILLE, PENNSYLVANIA.

IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No. 123,657, dated February 13, 1872.

' Specification describing `a certain Improvements in Sash-Locks, invented by WILLIAM C. YOUNG, of Danville', in the county of Montour and State of Pennsylvania.

l The nature of this invention consists in novelties in the construction and arrangement of thebolt, spring, and inclosing-case of the locks, which will be generally explained in the following description, and specifically pointed out in the claim.

' Figure'l is a front view of a window, the sash of which is provided with vmy improved look. Fig. 2 is a sectional elevation, on an enlarged scale, of the lock. Fig. 3 is a horizontal section thereof.

The same letters of reference are employed in all the figures to indicate identical parts.

A refers to the frame or case of the lock, which is inserted in a mortise in the edge of the stile of the sash, and further secured thereto by screws passing through flanges a of the case. The bolt B plays between guides of a of the case, and is projected,'through a suitable aperture in the edge of the case, by springs O G', which bear against 'the cross-bar B formed nponthe internal end of the bolt, as best seen v in Fig. 2. The springs are of the semi-elliptic kind, and are arranged back to back, so that they diverge from the center. The ends of the spring C are inpcontact with the rear edge l plate of the case, while the ends of the spring C bear against the cross-bar of the bolt, and are prevented from escaping from behind the same at the ends by short projections b b on the cross-bar, which serve to retain said spring y in proper position. The edges of the springs do not come in contact with the side plates of the case directly, but with low ribs c c and c o thereon, between which they are confined` .vided with a stud, D, which passes through an elongated slot in the stile of the sash and carries a knob, d, on its projecting end, by which the bolt may be retracted into its case. Mortises E are cut in the jambs of the Window, at suitable intervals, into which the bolt is shot by the action of the springs to sustain the sash at any desired elevation.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination, ina niortise sash-lock of a ease, A, guides a a', sliding bolt B, terminating at its inner end in a cross-bar b b, semielliptical springs (l C', and stud D, said springs being so arranged as to exerttheir entire force in the line of motion of the sliding bolt, all substantially as and for the purpose specified. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

v W. C. YOUNG.
